DSA overrides the master's ethtool ops so that we can inject its CPU
port's statistics. Because of that, we need to setup the ethtool ops
after the master's dsa_ptr pointer has been assigned, not before.
This patch setups the ethtool ops after dsa_ptr is assigned, and
restores them before it gets cleared.
